HEADLIGHT.

lApplication filed August 22, 1924. f Serial No. 733,511.

chief difculty is 'due to what is commonly referred to as the aging of the metal which manifests itself by splits and other defects due to the drawing' operation. These defects may occur at the time the lamp casing is manufactured but more often occur at some later time when the lamp is in use. It is the primary object of the present invention to overcome'the aforementioned defects by .constructing thelamp casing of a plurality of sections which areV clamped to-I gether so as to avoid the operations of soldering, brazing or similar methods .of uniting the parts together. Y

Another object is to provide a particularly simple and inexpensive method of constructf ing` the lamp casing so that the same maybe easilyassembled and which' shall'provide a dust-proof and water-proof housing for the lamp reflector and associated parts. c

Another object ris to provide a novel seal between the housing" and door so as to eX- clude dust, water and other elements from Aest the interior of the casing.

A. still further object is to provide a particularly simple and efhcient form of focusing device whereby the operator is provided a convenient means for focusing the lamp with respect to the reflector and the desired osition maintained.

With these and other objects in view, the.

invention consists in the various novel features of construction and arrangement or combination, all of which will be fully described hereinafter and pointed out in the claims appended hereto.

In the drawing accompanying and form-- ing a part of this application, Fig. 1 is a front elevation of a head lamp constructed in accordance with my invention; Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 1; Fig. 3 is a detail in plan showing the clamping means for retaining the parts of the. housing together; Fig. 4 is a fragmentary view in elevation of the cen tral portion of the rear of the lamp casing; and Fig. 5 is an end'elevation of thev focusing nut which is adapted to cooperate with thel portion of the'casing shownin-Fig. 4.

In constructing a lamp casing in accordance with -my invention,fI provide a rear section 1, a central section 2, and a front section 3. The rear section 1 is'pro'vided adjacent its peripheral edge with an inwardly turned portion 4 and -a rearwardly turned portion 5. The remainder 0f this rear section may be yof anysuitable shape for the purpose of ornamenting thev same and is shown as being provided with a circular bead portion 6 and an outwardly flared central portion 7. The central sectionA 2 ofthe lamp casing is substantially cylindrical in form and each peripheral edge thereof is ,deflected inwardly as indicated at 8 and then outwardly to define a collar lO. The for. ward-section 3 of the lamp casingr has the 'outer periph-eral edge thereof deected inwardly lto define'a flange 11 and the inner peripheral edge is turned inwardly as indicated at 12. A portion 13 intermediate thel inner and outer edges is embossed outwardly and provided with a plurality of apertures to receive the clamping bolts 14. In assembling the lamp casing thus far described the rear section isA fitted to one' end of the central section so that the inturn'ed portions 4 and Bof these sections are in Contact, and the collar 10 snugly .engages the rearwardly turned portion 5. The front section is fitted to the centralsection in a similar manner so that flange 11 engages collar 10 on thev opposite end of the'central section. rThe bolts 14 are then inserted through the aforementioned apertures in the embossed portion 13, and these bolts are threaded into suitable clamping irons 15, each of which is provided with a hook portion 16 which is adapted to enlOO gage in the channel defined by the inwardly and Yrearwardly turned portions of the rear section. The bolts are then tightened which serves to draw the sections in tight relation-` ship, and a lock nut 17 threaded on each bolt retains the parts inadjusted position.

A reflector 20 has the edge portion thereof provided with a plurality of inwardly directed tabs 21 which arev adapted to seat within apertures formed in the ffl-ont section 3 of the lainp casing and thereby prevent rotation and movement of the reflector with respect thereto. l

rPhe edge portion of'Ll the reflector is also provided with a plurality of outwardly d1- rected tabs 22 which, together with the niarginal portion 24 of the reflector7 define channel segments that receive a circular cork gasket 25,. The portions 26 of the reflector intermediate: the tabs 2l and 22 are adapted to contact with the lamp casing and thereby provide a, seat for the reflector.

4L-deer 27,"ot` suitable construction and having` af transparent pane 28, is hinged to the casing as indicated at` 279v and is adapted to Contactl with the cork gasket to forni a tight seal with the casing. Avsuitable latch 30'dis vpositioned dialnetrically opposite the hinge and serves to hold the 'door'in closed position. *A j rIhe central; section of the casing has an inner plateBl and an outer plate fastened thereto by means of' rivets and these plates serve tofasten an attaching lug 34 to the lamp casing, so thatthe saine may be supported on', the vehicle;

The focusing mechanism consists of' a larnp soc-liet sleeve-40 which is rig-idly fastened tov an arin 4l the rear end whereof is bent over and providedj with anaperture to receive a bolt 42 which is non-rotatively mountedtherein. rlhis bolt projects through the rear of the lainp casing andfis threaded into an adjusting nut 43 which, is swivelcdA in an aperture formed."` in the central portionoftlie rear section ofthe casing. Acoil spring 44 is interposed between the lainp casing and arnr 4l and serves to place a ten` sion on the threads ofthe bolt and adjusting nut. rllhecentralportion ofthe rear section ofthe la-lnpy casing is slightly depressed as indicated at l5-and' thisdepressed portion is providedln'fith a plurality of' embossed Steinispherical projections 46;- The facevofthe ad# justin'g nut which is incontact with the depressed' portion 45 is provided with a pluf rality of semi-spherical apertures 47 which are adapted to receiveV the projections 46 and thereby retain the parts in the Ydesired position. j

In operating the focusingadj ust-nient, itis only necessary'- to rotate theadjusting nut (which is preferably knurledl to afford an easy grasp for the operator) which in turn inoves the bolt 42, arin 41 and socket 40 longitudinally with respect to the refiector.
